LPR
Short for line printer daemon/line printer remote, a printer protocol that uses TCP/IP to establish connections between printers and workstations on a network. The technology was developed originally for BSD UNIX and has since become the de facto cross-platform printing protocol. The LPD software typically is stored in the printer or print server and the LPR software must be installed in the client device. The LPR client sends the print request to the IP address of the LPD printer/server, which in turn queues the file and prints it when the printer becomes available.
Server-Based Printing
In a Server-based Printing architecture, network clients send printing jobs to a server, allowing the server to queue printing jobs from multiple clients. The server then connects with print server unit to execute the various printing jobs. Server-based Printing alleviates network clients printing wait time and allow clients to seamlessly send simultaneous printing jobs, hence increasing your networks performance and efficiency.
